Moto Guzzi Norge GT 8V - vacuum gauge adapters.

Can anyone assist with a very quick answer confirming the Size and diameter of the screws you need to remove from the intake manifold to vacuum gauge adapters. I believe they are 6mm. Is that correct. I also need to know if they are a standard M6 pitch or if they are fine pitch. I am trying avoid buying an adapter that doesn’t fit. I have a ferret round in the forum and on parts lists etc but haven’t found and answer as yet.

You may find that they are M6 x 1.0 pitch - best bet is to get a bolt and try it before looking for an adaptor - my originals (for a 1200 8v) were made from a bolt drilled through the centre and a couple of O rings and nuts.

Guzzi do seem to favour the M6x1.00.

You know those retired, rusty old Brembo P06/08 bleed nipples ? That’s what I use…

Thank you for your advice. I purchased a couple off M6 X 1.00 adapters and they worked a treat.
